It’s not freaky and it’s not an optical illusion either. By staring at the black spot, the yellow sky and greenish pyramid is burned on your retina. When the colors dissapear, you see the “opposite” colors (blue and yellowish), and because underneath those color layer you see a picture of a pyramid, you have the impression that the pyramid is in full color. When you look away, you will notice that the colors move away too. There’s nothing freaky about this, it’s a totally natural and logical phenomena.
